Abstract

An armor panel comprising an armor member made of a laminated material, having a predetermined ballistic capability and a first flexural strength. The armor panel has a covering layer having a second flexural strength essentially lower than the first flexural strength. The covering layer is bonded to the armor member. The layer is made of a fiber reinforced material such that overall flexural strength of the armor panel is greater than twice the first structural strength. The overall ballistic capability of the armor panel is at least the same as that of the predetermined ballistic capability of the armor member.

Claims

1. An armor panel, comprising:

an inner armor member including a plurality of plies made of a material which is free of any metal or ceramics, said armor member being capable of withstanding a maximal bending load F1 applied thereto along a mid-line of the armor member oriented perpendicular thereto, said armor member having a predetermined ballistic capability B1; and

an external covering layer at least partially encapsulating said armor member, said external covering layer being formed of a fiber reinforced resin, the external covering layer being bonded to said armor member and having a thickness not exceeding 10% of that of said armor member and is not capable of withstanding the load F1 on its own;

whereby said armor panel is capable of withstanding a bending load F2>

2F1 applied thereto along the mid-line of the armor panel while having an overall ballistic capability B2, which is at least no less than B1.

2. An armor panel according to claim 1, wherein said armor panel is of a non-planar shape.

3. An armor panel according to claim 2, wherein said armor member has a non-planar shape.

4. An armor panel according to claim 3, wherein said plies are made of Polyethylene.

5. An armor panel according to claim 3, wherein said plies are made of several different materials.

6. An armor panel according to claim 1, wherein said external covering layer is formed of a fiber fabric prepreg.

7. An armor panel according to claim 6, wherein the weight area mass of fibers within the prepreg, ranges between 400 and 1000 g/m2.

8. An armor panel according to claim 1, wherein the fibers are made of Carbon or Aramide.

9. An armor panel according to claim 1, wherein the amount of resin within said prepreg is between 30-50%.

10. An armor panel according to claim 1, wherein the fibers of said fiber reinforced resin of said external covering layer are arranged in a uni-directional pattern.

11. An armor panel according to claim 1, wherein the fibers of said fiber reinforced resin of said external covering layer are arranged in a bi-directional pattern.

12. An armor panel according to claim 1, wherein the fibers of said fiber reinforced resin of said external cover layer are arranged in a woven-roving pattern.

13. An armor panel according to claim 1, wherein the load F1 is at least 50 kg.

14. An armor panel according to claim 1, wherein said external covering layer fully encapsulates the armor member.
